       8. An adjustable metal orthodontic band as defined in claim 1, wherein at least part of the corrugations are annealed. 
     
     
       9. An adjustable metal orthodontic band as defined in claim 1, wherein the corrugations are annealed. 
     
     
       10. An adjustable metal orthodontic band as defined in claim 1, wherein a plurality of sets of corrugations are provided. 
     
     
       11. An adjustable metal orthodontic band as defined in claim, wherein a set of corrugations is positioned on the lingual wall, and a horseshoe-shaped lingual cleat substantially surrounding the set of corrugations on three sides and secured to the band at its ends on the mesial and distal sides of the set. 
     
     
       12. A preformed adjustable metal orthodontic band for mounting orthodontic appliances on the tooth of an orthodontic patient comprising, a sleeve-shaped seamless body, said body having connecting walls, and means on at least one wall permitting expansion of the band to enlarge same to enable fitting teeth of various sizes, said means including a plurality of occlusogingival extending corrugations. 
     
     
       13. A preformed adjustable metal orthodontic band as defined in claim 12, wherein said means includes a plurality of sets of occlusogingival extending corrugations. 
     
     
       14. An adjustable metal orthodontic band for mounting orthodontic appliances on the tooth of an orthodontic patient comprising, a sleeve-shaped body, said body having walls adapted to engage buccal, lingual, mesial and distal surfaces of a tooth, and means on at least one wall including a plurality of occlusogingivally extending corrugations formed in the body permitting expansion of the band in at least the gingival portion thereof to enable fitting teeth of various sizes, said corrugations terminating short of the occlusal and gingival edges of the body. 
     
     
       15. An adjustable metal orthodontic band for mounting orthodontic appliances on the tooth of an orthodontic patient comprising, a sleeve-shaped body, said body having walls adapted to engage buccal, lingual, mesial and distal surfaces of a tooth, and means on at least one wall including a plurality of occlusogingivally extending corrugations formed in the body permitting expansion of the band in at least the gingival portion thereof to enable fitting teeth of various sizes, said corrugations extending from the occlusal edge of the body to a point intermediate the occlusal and gingival edges thereof. 
     
     
       16. An adjustable metal orthodontic band for mountinng orthodontic appliances on the tooth of an orthodontic patient comprising, a sleeve-shaped body, said body having walls adapted to engage buccal, lingual, mesial and distal surfaces of a tooth, and means on at least one wall including a plurality of occlusogingivally extending corrugations formed in the body permitting expansion of the band in at least the gingival portion thereof to enable fitting teeth of various sizes, said corrugations extending from the gingival edge of the body to a point intermediate the occlusal and gingival edges thereof. 
     
     
       17. An adjustable metal orthodontic band for mounting orthodontic appliances on the tooth of an orthodontic patient comprising, a sleeve-shaped body, said body having walls adapted to engage buccal, lingual, mesial and distal surfaces of a tooth, and means on at least one wall including a plurality of occlusogingivally extending corrugations formed in the body permitting expansion of the band in at least the gingival portion thereof to enable fitting teeth of various sizes, said corrugations extending from both the occlusal and gingival edges of the body to pints intermediate the occlusal and gingival edges thereof. 
     
     
       18. An adjustable metal orthodontic band as defined in claim 17, wherein the corrugations overlap at said points. 
     
     
       19. An adjustable metal orthodontic band for mounting orthodontic appliances on the tooth of an orthodontic patient comprising, a sleeve-shaped body, said body having walls adapted to engage buccal, lingual, mesial and distal surfaces of a tooth, and means on at least one wall including at least one occlusogingivally extending corrugation formed in the body permitting expansion of the band in at least the gingival portion thereof to enable fitting teeth of various sizes, said corrugation being non-uniform in depth along its length. 
     
     
       20. An adjustable metal orthodontic band for mounting orthodontic appliances on the tooth of an orthodontic patient comprising, a sleeve-shaped body, said body having walls adapted to engage buccal, lingual, mesial and distal surfaces of a tooth, and means on at least one wall including a plurality of occlusogingivally extending corrugations formed in the body permitting expansion of the band in at least the gingival thereof to enable fitting teeth of various sizes, and at least a part of the flat area between adjacent corrugations or at the gingival and/or occlusal ends of the corrugations is softer than the remaining parts of the band. 
     
     
       21. An adjustable metal orthodontic band for mounting orthodontic appliances on the tooth of an orthodontic patient comprising, a sleeve-shaped seamless body, said body having connecting walls adapted to engage buccal, lingual, mesial and distal surfaces of a tooth, said walls having common occlusal and gingival edges, and occlusogingivally extending corrugation means formed on the body prior to fitting that permits expansion of the band to enlarge same in at least the gingival portion thereof to enable fitting teeth of various sizes, said corrugation means defining a plurality of formations along a plane extending through the walls of the body and through said means and between the edges.
